A) which method can be used to prove the triangles congruent?

Angle RXQ is congruent to angle SXT because they are vertical angles and vertical angles are congruent now we can prove the triangles are congruent by SAS
triangle RXQ is congruent to triangle SXT

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
